Shallots and a touch of brown sugar bring out the sweetness in the beans.
2 pounds haricots verts (tiny green beans), trimmed
3 tablespoons butter
1 tablespoon light brown sugar
1 tablespoon olive oil
1 pound shallots, halved lengthwise and peeled
2 tablespoons red wine vinegar
Cook green beans in boiling salted water to cover 3 to 4 minutes or until crisp-tender; drain. Plunge beans into ice water to stop the cooking process; drain.
Melt butter and brown sugar with olive oil in a large skillet over medium-high heat; add shallots, and sauté 2 minutes. Reduce heat to medium-low, add vinegar, and sauté 10 minutes or until shallots are golden brown and tender.
Increase heat to medium-high; add green beans, and sauté 5 minutes or until thoroughly heated. Season with salt and freshly ground pepper to taste.
